The one thing life has shown me is by pension age you stop worrying. You aren't interested in having a new fitted kitchen or the latest gadgets and you end up spending less money. You spend more time appreciating things that don't cost a lot like gardening. All you want is a daily conversation, family and friends visiting and the odd day out. That's if you're lucky enough to reach that age.
My in laws are retired and spend money like water. Their house is all recently done up, they go on multiple holidays a year, day trips, mil loves shopping, they pay a ridiculous amount for Sky tv, they may not have the latest iPhones or gadgets but they certainly like to spend and experience things, within their means of course. They are boomers (nice ones

) who have done well with their investments and managed to retire relatively young in their mid/late 60’s. I do get where you’re coming from though. I’d imagine most of us youngsters will be working until at least 75. I’ve been a sahm for a few years now, just starting to think about finding work, so I reckon I’m completely
ducked as I’ll be only working part time anyway. I might look into a private pension if I can afford it. My partner has his work place pension but the predicted amount doesn’t look great, although they have different funds you can choose to invest in, some higher risk than others, and he wouldn’t lose the workplace contribution for switching around as its all under the company scheme. So that’s something I need to get him to look into as he’s on the one they put everyone on automatically which is relatively safe but low returns.
I only really started worrying about this kind of thing a couple of years ago (I’m 30). I really wish I was more informed/bothered about this stuff from a younger age.
